Raisable platform for stationary bikes

ABSTRACT

The Invention consists of a raisable platform for stationary bicycles, consisting of a special construction of the platform, of a rectangular general mounting provided with means for anchoring stationary bicycles of every type. This support pivots about its back end and has a forward placed pincers device with motorised opening that allows the raising of the mounting and the bicycle, imitating the different slopes of a trip.

PURPOSE OF THE INVENTION

[0001] The invention here proposed consists of a raisable platform forstationary bikes, among the means of support of articles for thepractice of stationary sports, of indoor track cycling and pursuit, ofconventional road bikes, mountain and recreational bikes, with orwithout rollers, or whatever other type of bike.

[0002] A special platform construction characterises this invention. Arectangular general mounting provided with means of anchoring stationarybikes of every type, capable of pivoting about the back end, and with aforward placed pincers device, with motorised opening for raising themounting and the bike, imitating the rises and falls of a trip.

BACKGROUND TO THE INVENTION

[0003] At present stationary bikes have supports pertaining to eachmake, with different construction and profile, even though practicallyall of them have double side supports, front and back.

[0004] The applicant does not know of the existence of platformsadaptable for any type of bike, and that, furthermore, imitate theunevenness of a theoretical trip, and that may be programmed by choice.

DESCRIPTION OF THE INVENTION

[0005] The invention that is the object of this report refers to araisable platform for stationary bikes, among all those means of supportfor articles for the practice of stationary sports, both in itsindividual application and collective use, coordinated or not, whichmight be gymnasiums or sport tournaments, indoor track cycling andpursuit, of conventional road bikes, mountain and recreational bikes,with or without rollers, or whatever other type of bike.

[0006] A special construction of the platform characterises thisinvention. This is made up of a rectangular general mounting, with abase plate and side metal strips, the longer of these being covered byconvex curved decorative covers, interchangeable between the two sides,and that delimit a general frame.

[0007] These curved sections, as well as avoiding tripping by the user,house in longitudinal cut-outs the front support wheels of the end of ametal section cut like a ratchet.

[0008] The base plate is provided with means for anchoring stationarybicycles of every type and this general mounting is capable of pivotingat the back end, about a base of a pair of irregular triangular plates,vertically supported, and the two sides with symmetrical cut-outs,having a rounded and holed upper projection, to accept a hinging pin,for the stated pivoting of the general mounting.

[0009] This invention has a casing, beside the short front side of thegeneral mounting, that incorporates means of raising, by means of aforward placed device with two pincers, positioned in a forward inclinedplane, with opposing mouths and with mutually self-embedding lips, withstep-by-step motorised opening, for the joint raising of the mountingand bicycle, imitating the rises and falls of a theoretical trip in theopen air.

[0010] For this, these pincers have, on their respective hinging axles,on one a rounded tubular housing with threaded interior that receivesthe axial advance of the other section of smaller diameter, with freepassage through the hinge of the opposite pincer which is connected withthe motor.

[0011] In this way the advance of the single or intermediate tubularsection of one of the pincers along the housing joined to the other,causes an opening of both opposing pincers to the maximum openingposition of these mouths.

[0012] The upper lips of both pincers are joined to a forward bridgethat supports their forward inclined and upper part and that is boltedto bolts that slide along the guide of a forward transverse metallicsection, preferably of aluminium, while this support triangulates in themost inner part by means of a obliquely positioned metal piece, lightlybent in the area of attachment to the bridge, and fully bent to thehorizontal in the lower area, fixed to the forward edge of the baseplate.

[0013] This triangular support strip, having its respective ends fixed,causes that the opening of the pincers forces the movement of the wheelsalong the curved section path, a drawing together of the pincers and,since the metal section in the shape of a ratchet is joined at itscentral part to a “U” for locking the lower lips of the pincers, througha intermediate transverse section, all of this causes the raising of theratcheted strip.

[0014] This raising causes the raising of the general mounting withrespect to the other end of this sheet section, free and connected to awheel, joined to the opposite section by a common axle which, in turn,moves towards the interior of the mounting projection, during itsraising, thus achieving the effects of progressive unevenness during thepeddling by the user of the stationary bicycle, until reaching 34° withrespect to the horizontal, easily controlled from a control incorporatedin the handlebars or remotely, by cable or by remote control, thepossibility existing that a central computer might program a largenumber of different rises and descents for a specific trip that mightreproduce the difficulties of a circuit, previously copying the ups anddowns of its route, and making the mounting follow, with the precisionrequired, the unevenness of each section, logically starting from a zerolevel that doesn't have and negative slopes.

PREFERABLE REALIZATION OF THE INVENTION

[0020] In view of what has been previously set out, this inventionrefers to a raisable platform for stationary bikes, among the means ofsupport of articles for the practice of stationary sports, essentiallycharacterised by having a rectangular general mounting (1) pivotingabout the back end, about a pair of irregular triangular plates (1.5),with a rounded and holed upper projection, to accept a hinging pin. Theplatform consisting of a base plate (1.1) with means of anchoring (1.4)stationary bikes (3) of every type and with side strips (1.2) and (1.3),with convex curved decorative anti-tripping covers (2) fitted to thelarger strips, without hand-holes, that delimit a general frame, withlongitudinal cut-outs (2.1) for housing wheels (4.1) of a metal section(4).

[0021] A forward casing incorporates pincers (6), in an oblique layout,with opposing mouths (6.1) and with lips (6.2) and (6.3) that mutuallyself-embed in pairs, activated by a conventional electric motor (7),either step by step or with limit of run, with axle (7.1) extended andextendible by screwing (7.2) through the hinge of one of the pincers (6)with free passage to a rounded tubular housing (7.2) positioned firmlyin the hinge of the opposite pincer, whose screwed position determinesthe opening of the opposing mouths (6.1) of both pincers (6).

[0022] The lips (6.2) of the pincers (6) are joined to a “U” (8.1) ofthe core of a forward support bridge (8), bolted to nuts (9.1) thatslide along the guide (9.2) of the forward edge (9) of the frame,preferably of aluminium; an inclined metal strip (10) fixed at the edgeof the base plate (1.1), complementing this support, so that the openingof the pincers (6) moves the wheels (4.1) along their path, based onwhich the metal sections (4) to whose ends they are attached, and thatfixed at the other end to a transverse section (12), also joined to the“U” (11) that holds the lips (6.2) and (6.3) of these means of raising,pivots in its centre, causing the raising of this metal section (4) andwith it the general mounting (1), that, in turn, pivots with respect tothe plate (1.5) and moving back the axle (4.2) of the forward wheels(4.1), producing an progressive unevening of the mounting (1) and withit, of the stationary bicycle (3), that reaches 34° with respect to thehorizontal.

[0023] The inclination of the mounting assembly (1) and bicycle (3) canbe set from a control incorporated in its handlebars or, for a group ofthese mounting (1) and bicycle (3) assemblies. It can be done remotely,by cable or by means of a remote control, and competitions and contestsor sport exhibitions with a variety of bike users could even be held, inwhich a central computer programs a specific trip that sets out a largenumber of different rises and descents for the specific trip thatreproduces the difficulties of a circuit, previously copying the ups anddowns of its route and causing the mountings to follow with the desiredprecision the unevenness of each stretch, logically starting from aninitial point that doesn't have negative slopes.

[0024] Variations in materials, shape, size and layout of the componentparts, described in a non-limiting way, do not alter the essentialnessof this invention; this being sufficient for its reproduction to beundertaken by an expert.
